Thermosensitive Liposome (TSL)

Target
TSL
Molecular classification
Lipid vesicle, Nanocarrier
01

Overview

Thermosensitive liposomes (TSLs) are engineered nanocarriers designed to release their encapsulated therapeutic agents in response to mild hyperthermia (39–42°C). They enable spatially and temporally controlled drug delivery, particularly for targeting tumors. Upon heating, the lipid bilayer undergoes a phase transition, increasing membrane permeability and releasing the drug. Different formulations exist, including traditional TSLs, lysolipid-containing TSLs (e.g., ThermoDox®), and polymer-modified TSLs.
